6 Claims. (oi. 62-102) This invention relates to freezing apparatus and it has for one of its objects the provision of simple, economical and eflicient means, preferably in the form of plates, associated with the cooling or freezing coils of the apparatus, the mentioned plates being preferably flat and in heat-conductive relation to the coils, whereby to provide for more rapid and therefore more efllcientcooling, the mentioned plates also being arranged to provide a sinuous air-course through theapparatus, which air-course further adds to the efiiciency ofthe apparatus.

Another object of the invention is the provision of means whereby the mentioned'plates may be readily connected to and disconnected from the cooling coils and in a manner to provide for increased heat conduction from the objects to be cooled or frozen, to the coils.

A further object of the invention is the provision of plates of the character mentioned, said vplates forming hollow bodies filling the spaces between the adjacent parts of the respective coils.

Other objects of the invention will be appreciated from a reading of the following specification. r

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with j the accompanying drawing which forms part of the application with the understanding, however, that the improvement is capable of extended applicationand not ooniinedto the exact showing of the nor to the precise construction'described and, therefore, mch changes a 88 and modifications may be made therefrom asdo not affect the of the invention nor exceed the thereof as expressed in the appended claims.

1 In the drawing:

Pig. 1 .is ahrdhen vertical section the freezingnapparatusembodying my invention, view showing :in side elevation a and pipes connected thereto and to cabinet of the apparatus; v g

l5 Fig. 2 is airagmentary horizontal section taken approximately on the line '2--'-2 of 1, looking in or arrows;

Fig. 3 a fragmentary section on 3-4 of Pig. 1, looking :in the direction of the arrows; and V 4 is a section similar to Fig. 3, but showing a modification of :my invention.

Referring to drawing :for a more detailed description the numeral 5 indicates a "56 cabinet in which positioned a p urality of horizontally disposed cooling or freezing coils 6, vertically spaced from each other and supported on angles 61:. In Figs. 1, 2 and 3, plates 7 are in contact with the tops of the coils 6, these plates being arranged in staggered relation so as m to provide a sinuous passageway or course through the cabinet 5. A blower 9 is connected to pipes 10 and 11 which open into the cabinet so that the blower may effect a circulation of air into the cabinet in the sinuous path mentioned, and also indicated by the arrows in Fig. 1. While the arrows indicatean upwardly traveling current, it is to be understood that a downwardly traveling cm'rentmay also be employed; The mentioned plates '7, beingflat, provide for a more eflicient cooling of articles placed thereon, than would be the case if the plates were omitted and the articles to be cooled or frozen were placed on the coils, this fact being readily appreciated by anyone skilled in the art when it is remembered that the coils and the plates are good heat conductors, being metallic.

The plates 7 are provided with means whereby they may be readily'connected to and disconnected from said coils, said means comprising pairs of cooperating resilient members 12 which may be snapped on to the coils 16 to securely hold the plates '7 to the coils. The edge portions of the plates '1 rest on angles 15, which are socured to the walls of the cabinet.

Referring now to Fig. 4, in which a modification of my invention is shown, a plurality of hollow bodies 16, preferably metallic, are provided between adjacent parts of the respective coils. Each of the hollow bodies 16 is preferably, but not necexarilv, formed from a single sheet of,

bent into the shape shown in Fig. 4

wherein the tops and bottoms of the hollow bodies are flat and the sides are concave, the tops being flat to effect increased eiliciency of the apparatus as explained above and the sides being concave to :dt thecoils which are herein shown as in cross-section, the hollow bodies being adapted to be sprung or snapped into position between the It will be noted that the, tops and bottoms of the hollow bodies 16 are respectivelyiiushed with the tops and bottoms of the coils B. I The coils 18 shown above the uppermost plates .7 are for the purpose explained in my 'copending application entitled .Freezing apparatus", m d October 5, 1931, Serial No. 567,0 which also applies to thecoils 19 disposed above the coils 18. "The clips 12, which extend the length of the coils provide for better conduction heat from the articles to be cooled 'or irozen to the cooling agent within the coils, it being evident that a larger heat conducting area of contact with the coils is provided by the clips than would be provided it the clips were omitted and conduction occurred only through the relatively small areas existing at the junction of the coils with the plates. The same increased conducting area is secured by the curved-sides of the hollow bodies 16. In lieu'of the hollow bodies 16, solid bodies may be employed. I I r What is claimed as new and useful is: 1. In freezing apparatus, a cabinet, a plurality of verticalli spaced, horizontal coils in said cabinet and plates adjacent said coils and ar-" ranged in staggered relation to provide a sinuous path for air, and snap clamping means for securing said plates to said coils.

2. In freezing apparatus, a cabinet, a plurality of vertically spaced, horizontal coils in said cabi net and plates adjacent said coils and arranged in staggered relation to provide a sinuous path for air, said plates defining hollow bodies filling the spaces between adjacent parts of the'respective coils. i

3. In freezing apparatus, a cabinet, a plurality of vertically spaced, horizontal'coils in said cabinet and plates adjacent said coils and arranged in staggered relation to provide a sinuous path for air, said plates defining hollow bodies filling the spaces between adjacent parts of the respective net and plates adjacent said coils and arranged to define horizontal passageways for air, there being openings provided for the passage of air from one of said passageways to another to provide a sinuous course for air, said plates defining hollow bodies filling the spaces between adjacent parts of the'respective coils, and adapted to be snapped into positionin contact with the respective coils. I

6. In freezing apparatus, a cabinet, a plurality of vertically spaced, horizontal coils in said cabinet and plates adjacent said coils and arranged in staggered relation to provide a sinuous path for air, and snap clamping means for securing said plates to said coils, said plates being at the tops and bottoms of said coils.
